In the technical scheme of the utility model, firstly, the sample to be solidified is placed in the transparent box body by opening the airtight cavity door, and the cavity door is closed; then, detecting the oxygen concentration in the transparent box body through an oxygen sensor, comparing the detected oxygen concentration with a preset value through a control chip, controlling an electronic valve to be opened through the control chip to introduce specific gas (for example, nitrogen) into the transparent box body when the oxygen concentration is higher than the preset value, simultaneously opening an exhaust hole to exhaust air, starting the program to expose the light curing equipment and controlling the exposure time when the oxygen concentration detected by the oxygen sensor is reduced to the preset value, and continuously introducing the specific gas during the exposure period until the exposure is finished; finally, the chamber door is opened to take out the sample. Thereby, a photo-curing process under protection of a specific gas atmosphere is achieved.
The utility model discloses a photocuring device is through automatic detection oxygen content or oxygen concentration and through letting in of controlling specific gas for treat that the solidification sample can carry out photocuring under the specific gas atmosphere protection that satisfies the condition.
As shown in fig. 1 and fig. 2, the transparent box 1 may have a two-layer cavity structure, wherein the upper layer cavity 13 may be used for placing the light curing device 3, and the lower layer cavity 14 may be used for placing a sample to be cured. In this case, the oxygen sensor, the vent hole and the exhaust hole are also disposed in the lower chamber 14 accordingly. It is understood that the structure of the transparent casing 1 is not limited thereto, and the transparent casing 1 may also be a single-layer cavity structure.
In practical applications, different light curing processes may need to be performed under different specific gas atmosphere protection, for example, nitrogen gas, helium gas atmosphere, etc. Since it is necessary to introduce a specific gas through the vent hole 10 and to discharge air through the discharge hole 11, in order to improve the ventilation and discharge efficiency, the arrangement positions of the vent hole 10 and the discharge hole 11 are preferably determined depending on the density ratio of the specific gas to the air. If the density of the specific gas is greater than that of air, it is preferable that the vent hole 10 is provided at a lower position of the lower chamber 14 and the exhaust hole 11 is provided at an upper position of the lower chamber 14, and if the density of the specific gas is less than that of air, it is preferable that the vent hole 10 is provided at an upper position of the lower chamber 14 and the exhaust hole 11 is provided at a lower position of the lower chamber 14.
In a further embodiment, in order to make the same photo-curing device applicable to photo-curing under different specific atmospheres, as shown in fig. 1, at least two vent holes 10 and at least two vent holes 11 may be provided on the transparent case 1 (specifically, the lower cavity 14), and at least one vent hole 10 is provided at an upper position of the lower cavity 14, at least one vent hole 10 is provided at a lower position of the lower cavity 14, similarly, at least one vent hole 11 is provided at an upper position of the lower cavity 14, at least one vent hole 11 is provided at a lower position of the lower cavity 14, and at least two vent holes may be provided with a switch valve.
In the above further embodiments, different vent holes 10 and vent holes 11 may be selected for use according to the needs of a particular gas atmosphere to improve venting and exhaustion efficiency. For example, when the density of the required specific gas is higher than that of air, it is selected to use the vent hole 10 at the lower position of the lower chamber 14 and the exhaust hole 11 at the upper position of the lower chamber 14; and vice versa.
In addition, it will be appreciated that, in order to ensure accurate detection of the oxygen content in the transparent enclosure, the specific location of the oxygen sensor 2 will also depend on the density contrast of the particular gas to air. In view of this, in a preferred embodiment, at least two oxygen sensors may be arranged in the transparent case 1 (specifically, the lower chamber 14), wherein at least one oxygen sensor 2 is disposed at an upper position of the lower chamber 14 and at least one oxygen sensor 2 is disposed at a lower position of the lower chamber 14. In this case, the exposure is performed only when the oxygen content or the oxygen concentration detected by the two oxygen sensors 2 simultaneously satisfies below the set value.
In practice, after the photo-curing of a certain sample to be cured is completed, the chamber door is opened to take out the sample, and the lower chamber 14 is returned to the air atmosphere during the process of opening the chamber door, so that the next sample to be cured can be put in, and the photo-curing control process as described above is repeated.
However, in some cases, it may be necessary to successively carry out photocuring under different specific gas atmospheres on the same sample to be cured. After photo-curing is performed under a specific gas atmosphere, the interior of the box body needs to be restored to an air atmosphere first, so that the concentration of other specific atmospheres can be controlled by detecting the oxygen content. In order to eliminate the action of opening the chamber door, in a preferred embodiment, an air inlet hole for introducing air can be further arranged on the lower chamber 14, and a switch valve is arranged at the air inlet hole.

So that the corresponding air inlet and outlet holes can be selectively opened according to the comparison of the density of the specific gas and the air in the box body.
Further, in order to reduce the manual intervention process and achieve automatic control of the light curing process, the switch valve may be an electronic valve in communication connection with the control chip, so that the on-off of the air inlet and the air outlet is automatically controlled by the control chip.
Further, the light curing device 3 further comprises a heat dissipation assembly and a light source, and the light source can be a linear light source or a surface light source. When a linear light source is adopted, the light curing device can perform scanning curing.
Further, the light curing equipment is light curing equipment under any wave band, working time and working power can be set, when the oxygen content sensor detects that the oxygen content in the sample cavity is lower than a preset value, the control chip controls the light curing equipment to be started, and the light curing equipment is closed after the working time.
In addition, as for the transparent case 1, it may be made of transparent material such as acryl, glass, etc.
The utility model has the advantages that:
1. the light curing equipment is combined with the specific gas atmosphere generating equipment, so that the requirement that the oxygen content in the atmosphere needs to be controlled under most light curing conditions is met.
2. The oxygen content sensor is arranged, the on-off of specific gas is intelligently controlled, the oxygen content in the atmosphere can be accurately limited, manual control is not needed, the operation is simple, the gas cost is saved, and the environment is not damaged.
3.
